According to BitMEX Research, the Bitcoin (BTC) Lightning Network faces significant security risks from future quantum computers, which could break its underlying ECDSA cryptography. The research outlines a detailed proposal for making Lightning Network transactions quantum-resistant by implementing post-quantum cryptography (PQC) standards, such as a one-time signature scheme. While this proposed upgrade could lead to larger transaction sizes and increased complexity, BitMEX Research emphasizes that it is a crucial measure to safeguard the long-term security of funds transacted on Bitcoin's primary layer-2 scaling solution.

According to @deanmlittle, ECDSA (Elliptic Curve Digital Signature Algorithm) is identified as a foundational component securing Bitcoin and other major cryptocurrencies, directly impacting trading security and transaction validation. Traders should note that ECDSA’s robustness ensures the authenticity of blockchain transactions, reducing risks of unauthorized trades and supporting market trust, as highlighted by the referenced tweet (Source: Twitter/@deanmlittle, May 9, 2025). This cryptographic standard underpins the reliability of crypto exchanges and wallets, making it essential for risk assessment and technical analysis in crypto trading.
